On July 4, John Williams made a special video appearance for PBS’ A Capitol Fourth concert, introducing the National Symphony Orchestra’s performance of the Main Theme from Superman. Here’s the transcript of Williams’ introduction and a video of the performance.

“In 1978 I was honored to compose the score for director Richard Donner’s wonderful film adaptation of Superman. The film starred among others Christopher Reeve, Gene Hackman, Margot Kidder, and the great Marlon Brando. But it was young Chris Reeve’s unforgettable performance in the title role that endeared this timeless character to movie audiences around the world.

This year, we celebrate not only the 40th anniversary of the film, but also the 80th anniversary of the first publication of the Superman comic books in 1938, which I remember. I’m particularly pleased that my music is part of this year’s Capitol Fourth celebration. And here’s maestro Jack Everly and our great National Symphony Orchestra in a special tribute to Superman.”
